In order to keep the antenna structure with good radiation signals under the condition of not additionally increasing the size of the electronic equipment, the antenna structure is installed on the outer surface of the middle frame to form the antenna component. The following description will be made in detail by taking an antenna assembly as an example.

Referring to fig. 6, fig. 6 is a first structure of an antenna assembly according to an embodiment of the present application.

The antenna assembly 500 includes a first substrate 510, a second substrate 520, and an antenna structure 530.

The first substrate 510 may be a plate-shaped structure. The first substrate 510 may be made of a metal material, such as magnesium alloy, formed by a die forming process, a die casting process, a machining process, or the like. It should be noted that the specific structure and material of the first substrate 510 can be adjusted according to actual needs. In some embodiments, the first substrate 510 may be connected to a ground terminal in a circuit board to ground the first substrate 510.

The second substrate 520 may be made of a plastic material, and may be formed on the first substrate 510 by injection molding, for example, to form a complete insert structure, or a middle frame structure. The second substrate 520 includes a frame 521 disposed on an outer side of the second substrate 520 and a connection structure formed on an inner surface of the frame 521.

Specifically, the second substrate 520 is fixedly connected to the first substrate 510, and the connection structure may be an earphone socket or a camera head socket. The second substrate 520 includes a frame surrounding the periphery of the first substrate 510.

In some embodiments, the bezel 521 includes a side frame and a corner portion 522, and the antenna structure 530 may be disposed at the side frame of the bezel 521, or at the corner portion 522, and the specific location may be determined according to the actual situation. In some embodiments, the rim 521 further includes a protrusion 5221, and the protrusion 5221 is located at the middle of the rim 521 in the width direction.

With reference to fig. 7, a structure of a second substrate provided in an embodiment of the present application is shown.

In some embodiments, in the antenna structure 530, the antenna structure 530 includes a first structure portion 531, a second structure portion 532, and a connection portion 533.

Wherein the first structure portion 531 is provided on the outer surface of the corner portion 522; the second structure portion 532 is provided on the outer surface of the corner portion 522. The first structure portions 531 and the second structure portions 532 are fitted into the grooves, for example, by grooving the outer surfaces of both sides in the width direction of the corner portions, and the specific fitting manner may be determined according to the actual situation, such as fitting and fixing the first structure portions 531 by a snap or a rivet. Or directly on the first structure portion 531, so as to form the frame 521 at the periphery of the first structure portion 531.

The second structure portion 532 is provided on the outer surface of the other side of the border 521 in the width direction with respect to the first structure portion 531, and the position and connection relationship between the second structure portion 532 and the corner portion or the side border can refer to the position and connection relationship between the first structure portion 531 and the corner portion or the side border.

The first structure part 531 and the second structure part 532 are respectively located on two sides of the protrusion part 5221. Specifically, the first structure part 531 and the second structure part 532 are distributed at intervals on both sides of the corner part 522 in the width direction, and the protrusion part 5221 is located between the first structure part 531 and the second structure part 532.

The connecting portion 533 is connected between the first structure portion 531 and the second structure portion 532. In some embodiments, the connecting portion 533 may be disposed on the inner surface of the second substrate 520, or the connecting portion 533 may be disposed in the second substrate 520.

Referring to fig. 8, a cross-sectional structure of a first portion of the second substrate 520 along a line P-P according to an embodiment of the present application is shown.

The antenna structure 530 also includes a feed structure 534 and a ground structure 535. The feeding structure 534 extends from the inner side of the antenna structure 530 and extends toward the inner side of the second substrate 520. For example, the feeding structure 534 may be a metal elastic sheet, and one end of the metal elastic sheet is abutted to the antenna structure 530, and the other end of the metal elastic sheet passes through the second substrate 520 and penetrates out of the second substrate 520 to be connected to a feeding interface on a circuit board, so as to implement feeding of the antenna structure 530 by an electronic device. Of course, besides the metal elastic sheet, other metal structural members may be used, such as a screw or a metal extension of the antenna structure 530, which is not limited herein.

The grounding structure 535 extends from the inner side of the antenna structure 530, and extends toward the inner side of the second substrate 520, and is connected to the first substrate 510. It is to be appreciated that when the first substrate 510 serves as the ground structure 535, the connection to the first substrate 510 may enable the antenna structure 530 to be grounded. It is understood that the grounding structure 535 is a metal structure, and may be a metal spring, a screw, or a metal extension of the antenna structure 530.

As can be seen from the above, the antenna structure 530 is disposed on the outer surface of the frame 521, so that the clearance area of the antenna structure 530 in the electronic device can be increased and the radiation signal strength of the antenna structure 530 can be improved under the condition that the size of the electronic device is not changed, and the probability that the antenna structure 530 is damaged due to falling can also be reduced because the antenna structure 530 is disposed on the outer surfaces of the two sides of the frame 521 in the width direction.

In some embodiments, referring to fig. 8, a bezel 521 is shown, the bezel 521 is located at a corner portion, the bezel 5210 includes a protrusion 5221, and an antenna structure including a first structure portion 531, a second structure portion 532, and a connecting portion 533. The first structure portion 531 and the second structure portion 532 are respectively located at two sides of the protrusion portion 5221. The antenna structure also includes a feed structure 534 and a ground structure 535. The connecting portion 533 is a metal sheet connected between the first structure portion 531 and the second structure portion 532, the connecting portion 533 can be disposed on the inner surface of the second substrate 520, or the connecting portion 533 is disposed in the second substrate 520, wherein:

the outer surfaces of the first structure portion 531, the second structure portion 532 and the protrusion portion 5221 form an arc surface together, and the outer surface of the frame 521 is located between the outer surfaces of the first structure portion 531 and the second structure portion 532. Specifically, the specific radian of the cambered surface can be determined according to actual conditions.

As shown in fig. 8, the vertical width between the outer surface of the first structure portion 531 or the outer surface of the second structure portion 532 and the inner side of the second substrate is W1, and the vertical width between the outer surface of the bezel 521 and the inner side of the second substrate is W2. As can be seen from the figure, the vertical width between the outer surface of the first structure portion 531 or the outer surface of the second structure portion 532 and the inner side of the second substrate may be set to be smaller than the vertical width between the outer surface of the bezel 521 and the inner side of the second substrate, i.e., WI < W2, so that the relatively higher bezel 521 can protect the first structure portion 531 and the second structure portion 532 on both sides and prevent the first structure portion 531 and the second structure portion 532 from being directly impacted.

For example, if the antenna structure is disposed at a corner portion, that is, the first structure portion 531 and the second structure portion 532 are disposed at two sides of the corner portion of the bezel 521, the probability that the protruded corner portion of the bezel 521 is a collision portion when the electronic device falls down may be greater, and the probability of damage to the antenna structure may be reduced.

In some embodiments, the first structure portion 531, the second structure portion 532 and the connecting portion 533 may be integrally formed structures, which enhances the strength of the structures.

In some embodiments, a plastic layer may be sprayed or injection-molded on the outer surface of the first structure portion 531, the second structure portion 532 and the rim 521 to enhance the integrity of the outer surface, and the plastic layer may also protect the first structure portion 531, the second structure portion 532 and the rim 521.

Referring to fig. 9, a second partial cross-sectional structure of the second substrate 520 along the line P-P according to the embodiment of the present application is shown.
